Hankook Ventus S1 evo 3 255/45 R18 Volkswagen Transporter 17,000 miles August 11, 2025
Decent, comfortable tires for a loaded campervan. The tires have lasted about 17-20k miles, which is amazingly good for a VW transporter. They are quiet, surefooted and not in the least noisy.

Hifly HF805 255/45 R18 Volkswagen Transporter 20,000 miles August 7, 2025
They were fitted to my coach converted VW T6 on collection, and lasted 20,000 and four and a half years before really bad wear and splitting on tires walls. They are a budget tire and you get what you pay for. I've replaced them with Royal Black Royal Explorer II's, again a budget tire but I only do 4,500 miles a year.

Michelin CrossClimate 2 255/45 R18 BMW 320d GT 8,000 miles September 30, 2024
Before purchase I liked the idea of a tire that I could trust in the snow but also performed well in the summer. I confess that, while I felt that the Cross Climate 2 / Cross Climate SUV would handle the snow, I worried that it might feel "soft" in warmer weather. Nevertheless, I went ahead.

As a BMW owner I tend to drive like an old man to work, then quite spirited on parts of a journey - then back to motorway speeds on motorways. It was for the moments of spirited driving, especially in hot weather, that I had concerns.

So, after almost 9 months, how have these stacked up? I am impressed, very impressed. Admittedly, last winter I didn't get to test the snow capabilities, but the all important summer, hot days, hot tarmac performance was exemplary. My fears were well and truly cast into the oblivion of potholes of which there are many locally. That brings me to comfort and noise. The tires proved both quieter and more comfortable than the Goodyear Eagle F1 Asymmetric 5's previously fitted, and they, themselves were better than BMW's run-flat choice. So, all in all, a win all around.

Currently, too, wear is good although they have needed one re-balance.

In summary, a great tire. Hopefully we'll get some snow this winter to try them at the other extreme, but as an excellent, all weather tire, working well in the cold, in heavy rain and on hot summer days I have no hesitation in recommending them. Would I buy them again if I change vehicle? Absolutely.

Nankang AS1 255/45 R18 Volkswagen Transporter 18,000 miles April 10, 2024
Installed on an always fully laden LWB VW T6 Transporter with lowered uprated suspension.
I am stunned at how well they have lasted and only one puncture and that was a nail, the van is driven off road onsite during the day. I use these rims and tires between March and October and then switch to winter rims and tires.
Only slight weakness is during torrential rain, but that probably says more about me than the tires; I will certainly buy again shortly.

Nexen N Fera SU1 255/45 R18 BMW 520i 35,000 miles February 20, 2024
My BMW 520 i F10 already had Continental Premiuncontact 3 runflat (SSR) about 5 years ago. They were already in a position to change due to wear and tear, perhaps it could have driven about 10,000 km more, but I preferred to change them and decided on the NEXEN Nfera SU1 and the change was total.
Much smoother and quieter than the Continentals, my driving is in the city and on the highway from time to time and the comfort is much better, 100% recommended, plus its price has nothing to do with the Continentals, the value of the NEXEN in Chile At least it is 50% of the value of the Continental.
I am very happy and satisfied, I recommend them.

Hankook Ventus S1 evo 3 255/45 R18 BMW i4 e40 11,000 miles January 4, 2023
This is an update on previous review. Wonderful tire. Travelled in rain, ice, dry, no issues at all at least for my lazy driving. Quiet, comfortable, breaks and corners as well as I would like. Wear not too good, down to 5 mm from 8 mm in 11k miles, I guess I am lucky to get 20k miles. Overall I d absolutely buy again unless another tire is equally good but with better wear

Kormoran Road Performance 255/45 R18 Mercedes Benz S500 6,000 miles June 14, 2022
Excellent tire, road noise is minimum and give a good firm but comfortable ride in all conditions ,these are fitted to a Mercedes S class limousine long wheel base and are the best tires I’ve had , better than the premium brands . The car has been driven in all conditions other than deep snow and fully do what is required .As a former professional driver who has had to drive in some awful weather conditions I fully recommend these tire and would certainly buy again and again. Don’t waste money on labels that are not as good , it’s money down the drain, these are made in the same factory as Michelin tires!!!

Kumho Ecsta PS71 255/45 R18 Mercedes Benz W221 S350 Long 16,000 miles March 17, 2022
Fitted these tires onto my black Mercedes S class on 25 January 2020 with, I assume, 8-9mm of tread. Just had car serviced, March 2022, & advised that tread depth now 1.9/2.1mm after 16,000 miles!!!!! They are on the rear & it's rwd BUT in January 2020 I was 73, not a boy racer. Oh, this is a high day/holiday car plus works as a funeral vehicle. I have another "banger" for general use/car park pings & dings! So, mostly driving reverently or motorway distances, (France/Germany). OK, on motorways abroad, when traffic permits, I'm cruising at 80/85mph, but surely that should be the easy bit for a tire. Anyway, as they're on the back, they felt fine but I've clearly left a 16,000 mile skid mark behind me! Advice, don't touch them with a barge pole, I won't again.
